Does the fan automatically come on in a power supply unit?
Yes
When do you need to replace the computer power supply?
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
The fan in a 250-watt power supply is malfunctioning. what action should you take?
Remove and replace the power supply.
Why should you have to check the power supply fan?
If it is a computer power supply then the fan is one of the main cooling fans for a PC. If it is not working then there is an extremely good chance that the system will overheat and shut down at best, be damaged at worst.
If your power supply's fan no longer works what is the best course of action?
Replace the power supply. Power supplies are pretty inexpensive and usually range $40-$60 for 400watts. Recommend you replace this as soon as possible. NOTE: the power supply is one of the four components which require a fan as it builds up alot of heat. The other three are processor, video card, and the case itself.
Does the fan automatically come on in a power supply unit?
Yes
Does the CPU supply provide power to a CPU fan or a case fan?
Neither, The CPU is the Central Processing Unit, it only processes information and bits of data the computer sends thru it. The motherboard supplies power to the case fan AND the CPU fan, which is supplied power from the PSU (power supply unit)

What help keeps a power supply from overheating?
The simplest way is that most power supplies have a built-in fan (or several) to keep them cool. If this fan is blocked, or the case airflow is going opposite to the power supply airflow (which typically pulls air from the case, out the back) then it can cause overheating. Lowering the power draw on the power supply will also reduce the amount of heat it produces, especially on the 12v rail.
What can you do to disable a computer that keeps starting up?
Take out the PSU (Power Supply Unit) It's the largest box inside your computer with a fan on it. Without power = no computer.
What does the CPU fan connect to?
The fans usually connect to the motherboard, but they can connect directly to the power supply unit.
What is the main purpose of a fan in the power supply on ATX systems?
cooling the power supply circuity
How can you tell if the power of the power supply is on?
Most have a fan in them and you can hear when it is on.
Does the power supply provide power to a CPU fan or case fan?
yes, the power supply provides power specifically to the motherboard in turn dispersing power to all components plugged into the motherboard, hope this helped :)
What does a power supply fan do?
A power supply fan keeps the power supply cool. The semiconductor components get hot in a switching power supply, and this fan keeps things cool and helps prevent the power supply from damaging itself from excessive heat. As an example, when you play games, the video card requires a lot more current. That means the power supply has to work harder. The switching transistors in the power supply have to operate at a higher frequency and pass electricity through them a higher percentage of the time. That in turn causes them to get hot. The fan helps pull this heat away and protects these components.
When do you need to replace the computer power supply?
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
